BEST MODE

Exemplary embodiments of the present invention will now be described indetail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view illustrating a configuration of aheat exchange ventilating apparatus according to an exemplary embodimentof the present invention.

Referring to FIG. 1, a ventilating apparatus 100 for total heat exchange(hereinafter, also referred to as a “total heat exchange ventilatingapparatus”) according to an exemplary embodiment of the inventionincludes a body housing 110, a first blower fan 121, a second blower fan122, a rotary-type total heat exchange element 130, a first covering140, a filter box 150, and a pre-filter 153.

The body housing 110 may have an inside inlet 111, an inside outlet 112,an outside inlet 113, and an outside outlet 114 formed therein. Thetotal heat exchange ventilating apparatus 100 may draw indoor air inthrough the inside inlet 111 and discharge the indrawn air outdoorsthrough the outside outlet 114. Also, the total heat exchangeventilating apparatus 100 may draw outdoor air in through the outsideinlet 113 and discharge the indrawn air indoors through the insideoutlet 112.

In the present embodiment, the body housing 110 may be divided into anupper body housing 110 a and a lower body housing 110 b. The upper bodyhousing 110 a is disposed in the direction of indoors and the lower bodyhousing 110 b is disposed in the direction of outdoors. The inside inlet111 and the inside outlet 112 may be formed in the upper body housing110 a, and the outside inlet 113 and the outside outlet 114 may beformed in the lower body housing 110 b.

According to this embodiment, the inside inlet 111 may be formed towardone side of the body housing 110 and the inside outlet 112 may be formedtoward the other side of the body housing 110. One and the other sidesof the body housing 110 may be opposed to each other. When the insideinlet 111 and the inside outlet 112 are opposed to each other, outdoorfresh air drawn in through the outside inlet 113 and inside outlet 112may be prevented from being immediately discharged through the insideinlet 111 and the outside outlet 114.

The body housing 110 may have first and second air flow paths formedtherein. The first air flow path may be formed between the inside inlet111 and the outside outlet 114 and the second air flow path may beformed between the outside inlet 113 and the inside outlet 112.

The first and second blower fans 121 and 122 may be disposed in thefirst air flow path formed between the inside inlet 111 and the outsideoutlet 114 and the second air flow path formed between the outside inlet113 and the inside outlet 112, respectively. According to thisembodiment, the first blower fan 121 may draw indoor air in through theinside inlet 111 and the first air flow path and discharge the indrawnair through the outside outlet 114. The second blower fan 122 may drawoutdoor air in through the outside inlet 113 and discharge the indrawnair through the second air flow path and the inside outlet 112.

The rotary-type total heat exchange element 130 includes a first areaand a second area and allows the first air flow path to pass through thefirst area and the second air flow path to pass through the second areathereof.

In this embodiment, the rotary-type total heat exchange element 130 inthe shape of disc is disposed perpendicular to the direction of the airflowing in the first and second air flow paths.

The indoor air drawn in through the inside inlet 111 may be allowed topass through the first area of the rotary-type total heat exchangeelement 130, and the outdoor air drawn in through the outside inlet 113may be allowed to pass through the second area thereof. The rotary-typetotal heat exchange element 130 may retain sensible and latent heatincluded in the indoor air drawn in through the inside inlet 111 by itsrotary motion, and transfer the retained sensible and latent heat to theoutdoor air drawn in through the outside inlet 113. Since the sensibleand latent heat included in the indoor air is transferred to the airdrawn from outdoors by the rotary-type total heat exchange element 130,the air discharged from the inside outlet 112 may have sensible andlatent heat closer to that of the indoor air rather than that of theoutdoor air.

In the present embodiment, the rotary-type total heat exchange element130 may have a flat disc shape. The indrawn outdoor air and indoor airmay be allowed to pass through the upper and lower surfaces of the totalheat exchange element 130. Here, when the disc-type rotary-type totalheat exchange element 130 is rotated around the central axis thereof,the sensible and latent heat of the indoor air passing through thedisc-type rotary-type total heat exchange element 130 may be transferredto the outdoor air passing therethrough. The rotary-type total heatexchange element 130 may be formed to have a plurality of layers. Byadditionally including the plurality of layers formed of loesscomponents, bamboo fiber, charcoal, or the like, the antibacterial anddeodorization function thereof may be enhanced with respect to the airpassing through the rotary-type total heat exchange element 130.

The first covering 140 may be connected to the first blower fan 121 andconstitute a part of first air flow path. In this embodiment, the firstcovering 140 may have one open side 141 connected to an intake part ofthe first blower fan 121 and the other open side 142 connected to thefirst area through which the first air flow path of the rotary-typetotal heat exchange element 130 passes. The first covering 140 may havedimensions such that it is narrowed according to air flow direction inthe first air flow path. That is, the dimensions may be such that theother open side 142 of the first covering 140 may be formed to be widerthan one side 141. As described in the present embodiment, when thefirst covering 140 has the dimensions such that it is gradually narrowedaccording to air flow direction, the intake efficiency may be enhancedwith respect to the indoor air flowing in the first air flow path.

The filter box 150 may be connected to the first covering 140 andconstitute a part of first air flow path.

In this embodiment, the filter box 150 may have one open side 151 facingthe other open side 142 of the first covering 140 and connected to thefirst area through which the first air flow path of the rotary-typetotal heat exchange element 130 passes and the other open side connectedto the inside inlet 111.

One side 151 of the filter box 150 may have dimensions corresponding tothose of the other open side 142 of the first covering 140 and contactthe other open side 142 of the first covering 140, thereby forming asingle air flow path.

Also, the filter box 150 has dimensions widened according to thedirection of air flowing in the first air flow path.

In the present embodiment, the rotary-type total heat exchange element130 may be disposed between one side 151 of the filter box 150 and theother open side 142 of the first covering 140.

Accordingly, the first air flow path is formed such that the air flowingtherein sequentially passes through the inside inlet 111, the filter box140, the rotary-type total heat exchange element 130, the first covering140, the first blower fan 121 and the outside outlet 112.

Meanwhile, the sections of the other open side 142 of the first covering140 and one side 151 of the filter box 150 in contact with the disc-typerotary-type total heat exchange element 130 may have a semi-circularshape. The sections of the other open side 142 of the first covering 140and one side 151 of the filter box 150 having the semi-circular shapemay cover a part of the disc-type rotary-type total heat exchangeelement 130. As described in the present embodiment, when one side 151of the filter box 150 and the other open side 142 of the first covering140 is shaped to conform to the shape of the rotary-type total heatexchange element 130, the leakage of indoor air flowing in the first airflow path formed of the filter box 150 and the first covering 140 may bereduced.

The pre-filter 153 may be installed in the open other side 152 of thefilter box 150. The pre-filter 153 filters the indoor air drawn inthrough the inside inlet 111 to thereby remove foreign objects includedin the indoor air. The pre-filter 153 may prevent the rotary-type totalheat exchange element 130 from being contaminated by the foreign objectsincluded in the indoor air.

The total heat exchange ventilating apparatus 100 according to thisembodiment may further include a second covering 160 disposed betweenthe second blower fan 122 and the rotary-type total heat exchangeelement 130.

The second covering 160 may prevent the leakage of air in the second airflow path formed between the outside inlet 113 and the inside outlet112. The second covering 160 may have one side 161 having an opening andconnected to an exhaust part of the second blower fan 122 and the otherside 162 contacting the rotary-type total heat exchange element 130.

Accordingly, the second air flow path is formed such that the airflowing therein sequentially passes through the outside inlet 113, thesecond blower fan 122, the second covering 160, the rotary-type totalheat exchange element 130, and the inside outlet 112.

Meanwhile, The section of the other side 162 of the second covering 160in contact with the rotary-type total heat exchange element 130 may havea semi-circular shape. The section of the other side 162 of the secondcovering 160 having the semi-circular shape may cover a part of thedisc-type rotary-type total heat exchange element 130, thereby reducingthe leakage of indoor air flowing in the second air flow path formed ofthe second covering 160.

The total heat exchange ventilating apparatus 100 according to thisembodiment may further include at least one purification filters 170disposed inside the second covering 160. The purification filters 170filter the air drawn from outdoors through the second blower fan 122.The at least one purification filters 170 may include known filtercomponents such as nano silver coating, charcoal components, bamboocomponents, or the like.

The total heat exchange ventilating apparatus 100 according to thisembodiment may further include a shielding part 180 encompassing theperipheral area of the rotary-type total heat exchange element 130. Theshielding part 180 may prevent outdoor and indoor air from beingcommingled and contaminated during total heat exchange in therotary-type total heat exchange element 130. In this embodiment, theshielding part 180 may have a dual structure.

FIGS. 2 (a) through 2(c) illustrate a first covering, a filter box and asecond covering used in a heat exchange ventilating apparatus accordingto another exemplary embodiment of the present invention.

Referring to FIG. 2 (a), a first covering 240 may constitute a part offirst air flow path expelling the indoor air outdoors by being formedbetween an inside inlet and an outside outlet of a body housing. Thefirst covering 240 may have one side connected to an intake part of afirst blower fan 221 and the other side having an opening. The firstcovering 240 may have dimensions such that it is narrowed according tothe air flow direction in the first air flow path. That is, thedimensions may be such that the other side of the first covering 240 maybe formed to be wider than one side. As described in the presentembodiment, when the first covering 240 has dimensions such that it isgradually narrowed according to air flow direction, intake efficiencymay be enhanced with respect to the indoor air flowing in the first airflow path.

Referring to FIG. 2 (b), a filter box 250 may constitute a part of firstair flow path connected to the first covering 240. In this embodiment,the filter box 250 may have one side opposed to the other side of thefirst covering 240 and the other side having an opening. One side of thefilter box 250 may have dimensions corresponding to those of the otherside of the first covering 240.

In the present embodiment, a rotary-type total heat exchange element maybe disposed between one side of the filter box 250 and the other side ofthe first covering 240. In this case, the other side of the firstcovering 240 and one side of the filter box 250 may have a sectionthereof corresponding to the shape of the rotary-type total heatexchange element. As described in the present embodiment, when one sideof the filter box 250 and the other side of the first covering 240 isshaped to conform to the shape of the rotary-type total heat exchangeelement, the leakage of indoor air flowing in the first air flow pathformed of the filter box 250 and the first covering 240 may be reduced.

Referring to FIG. 2 (c), a second covering 260 may constitute a part ofsecond air flow path drawn outdoor air in and transferring the indrawnair indoors. The second covering 260 may have one side having an openingand connected to an exhaust part of a second blower fan (not shown)drawing the outdoor air in. The other side of the second covering 260may contact a rotary-type total heat exchange element (not shown). Thesecond covering 260 may prevent the leakage of air in the second airflow path.

FIG. 3 illustrates a configuration of a heat exchange ventilatingapparatus according to another exemplary embodiment of the presentinvention. Referring to FIG. 3, a ventilating apparatus 100′ for totalheat exchange according to this embodiment may further include anintake/exhaust duct 101 as compared with the ventilating apparatus 100for total heat exchange of FIG. 1. Since the elements other than theintake/exhaust duct 101 are identical to those described in theaforementioned embodiment, a detailed description thereof will beomitted. Rather, the intake/exhaust duct 101 will be described in detailwith reference to FIG. 4.

FIG. 4 is a perspective view illustrating an intake/exhaust ductaccording to an exemplary embodiment of the present invention. As shownin FIG. 4, the intake/exhaust duct 101 includes an intake duct 102 andan exhaust duct 103. The intake duct 102 includes a first unit 102 a anda second unit 102 b and the exhaust duct 103 also includes a first unit103 a and a second unit 103 b. The first unit 102 a of the intake duct102 and the first unit 103 a of the exhaust duct 103 are combined tothereby form a combined part. The second unit 102 b of the intake duct102 and the second unit 103 b of the exhaust duct 103 are divided fromthe combined part, thereby forming a divided part. Particularly, eachunit of the divided part is bent from the combined part when dividedfrom the combined part.

When the intake/exhaust duct 101 is installed, the combined part ismostly located within a through-hole in a wall and the divided part islocated outdoors. For this reason, only a single through-holeperforation is required in the location of the combined part, andaccordingly, the number of through-hole perforations required as well asthe installation time needed may be reduced, as compared with the casethat the intake duct and the exhaust duct are separately installed.

Meanwhile, the combined part may have a cylindrical shape. In this case,since the combined part may have the same shape as that of thethrough-hole of the wall where the intake/exhaust duct is installed, thesize of the through-hole may be reduced and the space between thethrough-hole and the combined part may also be reduced.

Also, as shown in FIG. 4, the combined part may be formed by combiningthe first unit 102 a of the intake duct 102 and the first unit 103 a ofthe exhaust duct 103 to have a cross-sectional yin-yang shape. In thecase of having a cross-sectional yin-yang shape, air flow resistance(fluid resistance) in the unit of the same dimension may be minimized,and accordingly, the amount of air flow may be increased. However, theinvention is not limited thereto. The first unit 102 a of the intakeduct 102 and the first unit 103 a of the exhaust duct 103 may becombined while having a variety of cross-sectional shapes.

The divided part may be formed in such a manner that the second unit 102b of the intake duct 102 and the second unit 103 b of the exhaust duct103 may be directed in different directions. If the intake duct 102 andthe exhaust duct 103 are disposed outdoors to be directed in differentdirections, the air drawn into the intake duct 102 and the airdischarged from the exhaust duct 103 may be separately divided andprevented from being commingled. FIG. 4 illustrates that the second unit102 b of the intake duct 102 and the second unit 103 b of the exhaustduct 103 are directed in opposing directions, but the invention is notlimited thereto. If they are directed in different directions, it isconsidered to be within the scope of the invention.

Meanwhile, the intake duct 102 and the exhaust duct 103 may be formed ofpolyvinyl chloride (PVC). PVC has good malleability properties, so itmay facilitate the manufacturing of the intake/exhaust duct 101 withgreater ease. However, the invention is not limited thereto. The intakeduct 102 and the exhaust duct 103 may be formed of a metal such ascopper that provides good durability.

Also, the intake duct 102 and the exhaust duct 103 may be separatelymanufactured and subsequently bonded with an adhesive to form thecombined part. Alternatively, the intake/exhaust duct may beintegratedly manufactured.

Referring to FIG. 5, the ventilating apparatus 100′ for total heatexchange according to this embodiment may further include an adapterpart 105. FIG. 5 (a) schematically illustrates the adapter part 105combined with the intake/exhaust duct 101, and FIG. 5 (b) schematicallyillustrates the inner structure of the adapter part 105. As shown inFIGS. 5 (a) and 5 (b), the adapter part 105 may include an intake part106 connected to the end of the first unit 102 a of the intake duct 102and allowing air to be drawn from the intake duct 102, and an exhaustpart 107 connected to the end of the first unit 103 a of the exhaustduct 103 and allowing air to be discharged into the exhaust duct 103.The adapter part 105 may allow the intake/exhaust duct 101 to beconnected to another apparatus, thereby increasing the possibility ofits application.

The intake part 106 may include an element (shown as “A” in FIG. 5B)connected to the first unit 102 a of the intake duct 102 in theintake/discharge duct 101, whereby the intake part 106 together with thefirst unit 102 a of the intake duct 102 forms a path through whichoutdoor air is drawn into the heat exchange ventilating apparatusdisposed indoors. Likewise, the exhaust part 107 may include an element(shown as “B” in FIG. 5B) connected to the first unit 103 a of theexhaust duct 103 in the intake/discharge duct 101, whereby the exhaustpart 107 together with the first unit 103 a of the exhaust duct 103forms a path through which the indrawn air is discharged outdoors fromthe heat exchange ventilating apparatus.

FIGS. 5A and 5B schematically illustrate the heat exchange ventilatingapparatus including the adapter part according to an exemplaryembodiment of the present invention. However, the invention is notlimited thereto. Rather, the ventilating apparatus may be connected toeach of a separate intake duct and a separate exhaust duct, and thus airmay be separately drawn in or discharged.

Meanwhile, although not shown in FIG. 3, the ventilating apparatus 100′for total heat exchange may further include a cover part which coversthe divided part of the intake/exhaust duct 101. The cover part coversthe divided part of the intake/exhaust duct 101 that may be exposedoutdoors when the ventilating apparatus 100′ for total heat exchange isinstalled, thereby making the unit presentable and protecting theintake/exhaust duct 101.

FIG. 6 is a perspective view schematically illustrating a cover partaccording to an exemplary embodiment of the present invention. As shownin FIG. 6, a cover part 104 covers the divided part formed of the secondunit 102 b of the intake duct 102 and the second unit 103 b of theexhaust duct 103. In the cover part 104, the parts corresponding to thesecond unit 102 b of the intake duct 102 and the second unit 103 b ofthe exhaust duct 103 may have nets or grills allowing for the intake anddischarge of air. Since the divided part disposed outdoors is covered bythe cover part 104, a presentable appearance may be realized and foreignobjects included in the outdoor air may be prevented from being drawn inthrough the intake duct 102.

In the enlarged view of FIG. 6, only one part of the cover part 104,corresponding to the second unit 102 b of the intake duct 102, isillustrated to have a net or grill. However, the other part of the coverpart 104, corresponding to the second unit 103 b of the exhaust duct 103in an opposing direction, also has a shutter.

As set forth above, a heat exchange ventilating apparatus according toexemplary embodiments of the invention allows for the enhancement ofintake/discharge efficiency by varying its inner structure.

Also, when installed, a heat exchange ventilating apparatus according toexemplary embodiments of the invention reduces the number of holes to beperforated.
